Set the file permission bits of created directories to mode,
which uses the same syntax as
in chmod and uses ‘a=rwx’ (read, write and execute allowed for
everyone) for the point of the departure. See File permissions.

Normally the directory has the desired file mode bits at the moment it
is created. As a GNU extension, mode may also mention
special mode bits, but in this case there may be a temporary window
during which the directory exists but its special mode bits are
incorrect. See Directory Setuid and Setgid, for how the
set-user-ID and set-group-ID bits of directories are inherited unless
overridden in this way.

‘-p’

‘--parents’

Make any missing parent directories for each argument, setting their
file permission bits to the umask modified by ‘u+wx’. Ignore
existing parent directories, and do not change their file permission
bits.

To set the file permission bits of any newly-created parent
directories to a value that includes ‘u+wx’, you can set the
umask before invoking mkdir. For example, if the shell
command ‘(umask u=rwx,go=rx; mkdir -p P/Q)’ creates the parent
P it sets the parent's permission bits to ‘u=rwx,go=rx’.
To set a parent's special mode bits as well, you can invoke
chmod after mkdir. See Directory Setuid and Setgid, for how the set-user-ID and set-group-ID bits of
newly-created parent directories are inherited.

‘-v’

‘--verbose’

Print a message for each created directory. This is most useful with
--parents.

‘-Z’

‘--context[=context]’

Without a specified context, adjust the SELinux security context according
to the system default type for destination files, similarly to the
restorecon command.
The long form of this option with a specific context specified,
will set the context for newly created files only.
With a specified context, if both SELinux and SMACK are disabled, a warning is
issued.

An exit status of zero indicates success,
and a nonzero value indicates failure.
